Frequently Asked Questions

1. What is the difference between HH15, HH15A, and HH15P models?

HH15 refers to the standard single or dual throw switch. HH15A features a contact series structure, while HH15P utilizes a contact parallel structure for higher current capacities and different mechanical performance.

2. What are the rated insulation and working voltages?

The HH15 series has a rated insulation voltage (Ui) of 1000V and a rated working voltage (Ue) of AC400V or 690V. Some configurations also support DC-23B at 250V/500V.

3. How many poles are available for these disconnect switches?

Most models are available in 3P, 4P (with switchable neutral), and 3N (4P with fixed connection neutral pole) configurations to meet various wiring standards.

4. Can the switch be operated from inside the electrical cabinet?

Yes. By selecting the 'T' additional note option during selection, the product is configured for operation inside the cabinet. The default configuration is for operation outside the cabinet.

5. What is the expected mechanical life of the HH15 series?

Mechanical life varies by current rating: smaller units (63-125A) offer up to 15,000 operations, while larger industrial units (over 1000A) range from 300 to 3,000 operations.

6. Are auxiliary contacts available for status monitoring?

Yes, models can be equipped with 'L' (1 pair of auxiliary contacts) or 'Z' (2 auxiliary contacts) options. The auxiliary contacts have a heating current rating (Ith) of 5A at 380V AC15.
